lsm: Fit a Latent Space Model for a Binary Network

In kisungyou/T4network: Tools for Network Analysis

Description

Fit a Latent Space Model for a Binary Network

Usage

lsm(graph, ndim = 2, nstart = 5)

Examples

## load the karate club data
data(karate, package="T4network")

## compute 2-dimensional latent space
lsm.embed = lsm(karate$A, ndim=2)

## prepare for plotting with 'igraph' with fixed layout
obj.igraph = igraph::graph_from_adjacency_matrix(karate$A, mode="undirected")

## visualize
opar <- par(no.readonly=TRUE)
par(mfrow=c(1,2))
plot(obj.igraph, vertex.color=karate$label, vertex.label=NA, 
     main="igraph visualization")
plot(obj.igraph, vertex.color=karate$label, vertex.label=NA,
     layout=lsm.embed$latent, main="Latent space embedding")
par(opar)
